Latest Patents

Jian Weng holds a patent for a Phase Modulation Spectroscopic System. This system utilizes two laser diodes that emit radiation at specific wavelengths, approximately 754-760 nm and 816-840 nm. The laser diodes are modulated sinusoidally at around 220 MHz. The signals from these diodes are transmitted to the subject through a bifurcated plastic optical fiber with a diameter of 1 mm. After passing through the subject, the signals are detected by a Hamamatsu R928 photomultiplier, which generates two experimental signals. These signals are then compared to a reference signal in a phase detector, allowing for the correlation of phase shifts to specific pathophysiological conditions.
